I'm not a lawyer but I can tell you what has happened here in Powell, WY. There was a raid, the warrent was issued to the correct house, but for the wrong person (mistaken identity, first names the same, same race, last names different), in the house were several people, the renter, a cousin, a friend, a inside narc., another friend and two 16 year old's. When the door was busted open stuff went every where, one sixteen year old was clean but ticketed for tabaco because it was tangled in his coat when the scuffle was over, the other sixteen year old had a needle (clean), and a very small amount in her purse. The renter is not being charged due to the wrong warrent (we assume), the cousin is being charged with possesion of smoke (a ounce), the narc. made excuses and was allowed to leave, the friend was in the shower and isn't being charged, the other friend is being charged with intent to deliver smoke because he admitted to passing a joint, the 16 year old girl spent 3 days in jail for using her miranda rights to wait for her lawyer, is now in the girls shelter and will remain there until she goes to court in two more months and is being charged with intent to deliver several 8 balls. It is not hers and they didn't find it on her, but they have to charge somebody.
Good Luck!!!
